Kozmová, Monika ; Tufano, James Joseph (advisor) ; Šteffl, Michal (referee)
Title: Obstacle course racing: the effect of obstacles on the total race time during a Spartan Race Objectives: The aim of this study was to determine the effect of 30-burpee punishment on subsequent running speed (SPD), heart rate (HR) following a missed obstacle, and the final race standings during a OCR race. Methods: In our thesis we used a method of analysis in an official Spartan Race in the Czech Republic. 11 male OCR competitors wore a GPS and HR monitor, from which HR and SPD were measured. Three specific obstacles were chosen where nearly all competitors did burpees (spear throw), half did burpees (traverse wall), and nearly none did burpees (monkey bars). The HR and SPD were measured during the entire race, and specifically noted when the competitors arrived at left the obstacle. Results: The average HR of the entire race was 166.45 ± 3.34 beats per minute. The average time spent at the successful obstacles without burpees was 23 ± 17 seconds, while the average time spent at the unsuccessful obstacles with burpees was 124 ± 11 seconds. The change in HR over the course of successful obstacles was 0.79 ± 3.69 beat per minute, while the change in HR during unsuccessful obstacles with burpees was -3.00 ± 6.70 beat per minute. Total time spent at each obstacle correlated with the final...

Šablatúra, Michal ; Šteffl, Michal (advisor) ; Kočíb, Tomáš (referee)
Title: Diagnostics of the asymmetries of the deltoid muscles of table tennis players by using tensiomyography. Objectives: The aim of this bachelor thesis was to define the hypothesis about the impact of table tennis on the musculoskeletal apparatus, to determine muscle dysbalance and select suitable exercises for improvement. Methods: This is a case study. The research is done qualitatively by mapping a small number of probands. Six selected individuals were measured, the results were analysed and according to this the recommendations were made. The tensiomyograph TMG 100 was used to diagnose muscular asymmetries in the deltoid muscle. Results: From the measurements of six probands was found that the greatest asymmetry was in the lateral part of the deltoid muscle. Because of the greater flaccidity of a non-playing arm, four probands were recommended to do strengthening exercises and three probands were recommended to do activation exercises on their non- playing arm. At the front of the deltoid muscle, two probands had a shortened muscles on a playing arm and a flapless non-playing arm, so they were recommended to perform strengthening exercises on non-playing arm and stretching exercises on the playing arm. At the back of the deltoid muscle, the players had different results in muscle imbalance,...

Malý, Matěj ; Šteffl, Michal (advisor) ; Petr, Miroslav (referee)
Title: The current view of protein intake in power athletes - a review study. Objectives: Based on literary sources and professional studies, the aim of my work is to work out, systematically organize and compare acquired knowledge in the field of nutrition in power sports, namely the intake of proteins. Methods: The thesis is based on an review study, which, based on a uniform methodology of searching on three professional servers, processes and compares the results of the studies. Conclusion: Most studies coincide with the positive effect of increased protein intake on body composition. However, determining the exact optimal number of proteins taken for strength athletes is an individual matter that depends on many subjective factors. The harmful effects of the long-term professional high-protein diet have not been confirmed as well as its effect on physical performance and regeneration. Keywords: nutrition, high protein diet, resistance training, body composition, regeneration, metabolic response
